FINKLESTEIN, O11 DORCHESTER, MASSACHUSETTS, ASSIGNOB TO SUNSHIN INCORPORATED, 0F LYNN, MASSACHUSETTS, A CORPORATION e LIGHT amnncron Application filed March 10, 1928.

My invention relates to light reflectors of the type adaptable for use with electric bulbs, for flood-light and other purposes, and has for its object to provide a reflector having a reflecting surface composed in part at least of a plurality of formations adapted to refleet light from one another and in various directions, whereby the light is broken up and diffused and thereby rendered soft and non-glaring.

I accomplish the objects of my invention as shown in the accompanying drawings in which Figure 1 is an interior View of my reflector. Figure 2 is a longitudinal sectional View thereof. Figure 3 shows an optional form of reflecting construction and Figure 4 is a longitudinal section of the optional form shown in Figure 3.

Referring again to Figures 1 and 2, A shows the are shaped rings formed to encircle the reflecting surface, each one of which rings makes marginal contact with the adjoining ring. B shows the enlarged arc ring shaped to receive the illuminant bulb.

C shows the ventilating orifices. D shows the canopy arranged to cover and protect the orifices from drafts and sudden changes in temperature. E shows the illuminant ordinarily an electric bulb.

Referring again to Figures 3 and 4, A shows pro ections of frustro-pyramidical shape raised upon the reflecting surface in rows positioned between the rings A, which are of V-shaped cross section and adapted, by reflecting the light between one another, to break up and diffuse the light.

While I have illustrated and described a preferred construction for carrying my invention into effect, this is capable of variation or modification without departing from the spirit of the invention. I therefore do not wish to be limited to the exact details of construction herein set forth but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention I claim as new and desire to secure by Letters Patent of the United States of America:

1. A light reflector comprising a hollow Serial No. 260,649.

member, means at the inner end of said member for retaining a light bulb therein, said member flaring towards its outer end, and a plurality of formations of frustro-pyramidical shape constituting a major portion at least of the inner reflecting surface of said member.

2. A light reflector comprising a hollow member, means at the inner end of said member for retaining a light bulb therein, said member flaring towards its outer end, and a plurality of formations of frustro-pyramidical shape constituting a major portion at least of the inner reflecting surface of said member, said formations being arranged in a plurality of separate rows extending around and spaced longitudinally of the reflector, the inner face of said reflector between each adjacent pair of rows of said formations being constituted by a pair of meeting surfaces extending around the member contiguous to said rows of formations and converging inwardly towards one another.

In testimony whereof I affix my signature.

EVERETT L. FINKLESTEIN.
